Problems solved by technology

On the one hand, it leads to a decrease in the yield of paper base, on the other hand, it increases the pressure on the sewage treatment system
In addition, due to the low index such as paper base bulk thickness, the coating rate is low, and the total yield of flakes is also low.

Abstract

The invention provides a preparation method of a tobacco sheet. The preparation method of the tobacco sheet includes the following steps: 1) mixing tobacco stems with hot water of 75-80 DEG C for extraction, and then squeezing to obtain tobacco stem extracting solution and tobacco stem filter residues; 2) mixing tobacco powder with hot water of 70-75 DEG C for extraction, and then squeezing to obtain tobacco powder extracting solution and tobacco powder filter residues; 3) mixing the tobacco stem extracting solution with the tobacco powder extracting solution for decompression concentration so as to obtain concentrated solution; 4) adding water into a mixture of the tobacco stem filter residues and the tobacco powder filter residues for fiber decomposition, and then adding complex enzyme preparations for pulping so as to obtain pulp materials; and 5) adding polymeric aluminum into the pulp materials for manufacturing paper with pulp so as to obtain a sheet paper base, then coating the sheet paper base with the concentrated solution, and drying to obtain the tobacco sheet. According to the preparation method of the tobacco sheet, the complex enzyme preparations are added after fibers of the tobacco stem filter residues and the tobacco powder filter residues are decomposed, and performance of the pulp materials is improved, pulping energy consumption is reduced, and the sheet yield is improved through synergistic effects among a variety of enzymes.

Description

technical field [0001] The invention relates to the field of tobacco sheets, in particular to a method for preparing tobacco sheets. Background technique [0002] Due to the advantages of low density, good mechanical properties and low tar release rate, paper-making tobacco sheet is being more and more widely used in the cigarette industry. The typical production process of paper-making tobacco flakes in China is to extract the water-soluble substances in tobacco powder and tobacco stems with water, and after solid-liquid separation, the solid part is made into paper base after pulping, while the liquid part is concentrated and then coated onto on paper base. Due to the short tobacco stem fiber, high content of miscellaneous cells, lignin, hemicellulose and pectin in the pulp, the quality of the pulp is hard and brittle, and it is not easy to fibrillate. In order to make the paper-forming performance of the tobacco stem fibers meet the requirements after beating, a large a...
